David is designing a t-shirt for the choir pop show. The cost of printing is $400 plus $7.50 per shirt. What is the average total cost per shirt if 85 shirts are sold? Round to the nearest cent.

im not quite sure if this is right but i got 5.6 oisutuve

step-by-step explanation:

i believe the answer is the polygon, heptagon.

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
